Can anyone point me to info on where and when patches like RSS Feed

towards the

me that
some patches are disallowed in the QC WebKit plugin. And I know
empirically
that content from an RSS Feed is not available when I Export as
QuickTime
Movie in the Quartz Composer UI, so I guess that qualifies as another
restricted enivronment. But this doesn't tell me how to predict
when such
patches are restricted. Hopefully it's not "don't except RSS Feed
to work
anywhere outside of the Quartz Composer viewer window."
The only restricted contexts are when embedded in a Quicktime Movie
and when playing back through Webkit (which includes Dashboard).
Quicktime Player additionally denies access to particular URLs, which
is why RSS doesn't work.
If your not inside webkit, and you have the Quartz Composer document
directly, then you should find that nothing is restricted.
What I ultimately need to know is what problems I should anticipate
when I
try to do offline rendering of compositions in my own application.
Inside your own application you should not see any restrictions on
the patches that can be run. Only if you go through Quicktime or
Webkit should you see any restrictions on what you can do.
The exact list of what patches are and are not allowed as of Mac OS X
10.4.7 are available here:
